GRAIN-MEASURER.

SPECIFICATIOTI forming part of Letters Patent No. 762,217, dated June 7, 1904.

Application filed January 20,1904. Serial No. 189,827. (No model.)

To all whom, it may concern:

Be it known that I, JOSIAH M. WELBOURN, a citizen of the United States, residing at Edison, in the county of Morrow and State of Ohio, haveinvented new and useful Improvements in Grain-hleasurers', of which the following is a specification.

My invention relates to improvements generally in grain-measurers, more especially, however, to that class applicable to threshingmachines.

It has for its object, among other things, to provide for the automatic actuation of the parts involving the delivery of the grain from the threshing-machine, the tripping or tilting of the grain receiving or measuring receptacle or cylinder at the prescribed interval, as whenemptying the respective compartments thereof, and the intermittent axial movement or rotation of said receptacle or cylinder.

A further object of said invention is to effect the automatic stroking 01f or removing the surplus or overflow grain as each measuring-cylinder compartment fills, this being so provided for that the overflow or stroked-off grain shall be caused to enter a subsequent or successive compartment. It is also noted in this connection that as the already or previously filled compartment is discharging the compartment which has received such surplus or stroked-off grain is being filled or supplied with grain. Provision is also made herein for the ready loading of the grain upon a wagon or like means for removing or transporting it to any suitable point or destination.

The nature of said invention consists of sundry parts, including in a restricted degree the construction and disposition thereof, substantially as hereinafter more fully disclosed by the following description, and particularly pointed out by the claims concluding said description.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a. side elevation thereof, certain parts being broken away. Fig. 2 is a plan view of the same, certain parts also being broken away. Fig. 3 is a horizontal section produced through the grain-measuring cylinder or receptacle. Fig. 4 is a detached plan view of said cylinder or receptacle, disclosing more especially the equilateral triangular cam-groove arrangement thereof. Fig. 5 is an inverted or bottom view of said cylinder or receptacle. Fig. 6 is a vertical section produced through said cylinder 0r receptacle transversely [of the stroking off device or scraper and through certain other adjunctive parts of said cylinder or receptacle. Fig. 7 is an enlarged detailed transverse section of the ratchet, pawl, and pinion or sprocketwheel arrangement coacting with certain other parts to effect the actuation of the grainmeasuring cylinder or receptacle. Fig. 8 is a view showing the parts of the latter figure disassembled or in detail. Fig. 9 is an enlarged detail section showing more particularly the swiveled or pivotal connection between the conveyer or elevator taking the grain from the measuring cylinder or receptacle and the chute or arm of said elevator or conveyer. Fig. 10 shows views of the respective parts forming said. pivotal or swiveled connection disassociated or disconnected one from the other.

1n the carrying out of my invention I suitably secure in a fixed position upon, say, the top portion or deck of a threshing-machine an elevator or conveyor 1, adapted, as usual, to take the grain from such machine, said elevator or conveyer having suitably secured thereto at its upper end a downward and outward inclined arm or chute 1, with its lower or discharging end juxtaposed to the grain-measuring receptacle or cylinder 2 and delivering thereinto, as presently seen. Said measuring receptacle or cylinder2 is axially or centrally pivotally supported upon amutilated disk or plate 3, having a central pivot stud or pin 3 entering a corresponding socket 3 in the center of the bottom of said cylinder. To

said plate or disk upon its under side are secured upward-extending lateral arms or bars 3 pivotally connected, as at 3, to a brace or support 3 suitably secured to the housing or casing of the elevator l and by means of which arrangement said measuring-cylinder is permitted to be tilted at certain intervals, as made more fully apparent hereinafter, for the discharging of the contents of the compartments of said cylinder. To the upper ends of said arms are connected or pivoted the lower ends of the arms of a bail-shaped lever 4, suitably fulcrumed upon, preferably, a bracket r secured to the casing of the elevator l. Said receptacle or cylinder is divided up into a number of compartments 2, each of equal holding capacity and each having a hinged or pivoted bottom plate 2", with its hinge or pivot arranged under a forward and downward inclined fixed plate or guard 2 housing the same as against the contact of the grain therewith. Said pivoted bottom plates are normally retained in position with relation to the compartments of the measuring-cylinder as against the grain escaping therefrom by means of the mutilated disk or supplemental bottom plate 3, before referred to, while by the mutilation of the last-named part produced by the removal of a segment therefrom, as at 3, an opening is provided below the bottom of said cylinder or receptacle at its discharging or delivery side. By this arrangement it will be seen that as the respective compartment bottom plates successively come oppositethe opening aforesaid, as when the measuringcylinder is revolved, as presently disclosed, said pivoted plates or bottoms 2" will successively drop orincline downward and forward, allowing, as is apparent, the discharging of the contents of the compartment alining said opening.

The lever or pivoted frame 4 has its outer arm 1 of suitable length for the intended purpose-" 1:. 0., to effect, with a weight 4 removably held thereon by a set-screw or otherwise,the automatic return or restoration of the measuring cylinder or receptacle to its horizontal or original position after having been tilted, as will be more fully apparent presently.

Just above the measuring cylinder or receptacle 2, with its bottom edge just about flush with the top edge of said cylinder, is a stroke-off device or scraper 5, suitably secured in place, say, to one of the arms 3", and is preferably arcuate in horizontal section and is open at top and bottom, it being constructed or produced in any suitable way with these ends in View. Therefore the grain from the chute 1, with its lower end arranged just above and in alinement with said stroke-off device or scraper 5, will be delivered through the last named into themeasuring cylinder or receptacle, so that just as the compartment below said scraper begins to be carriedfrom under said scraper, although the grain continues to flow, as it does, all grain in excess of what is required to lill said compartment will be thus automatically scraped off or removed by said scraper into the succeeding compartment, as is obvious.

Suitably journaled upon the housing or casing of the elevator 1 1s a shaft 6, bearmg a pinion or sprocket-wheel 7 belted, as at 7,

with a pinion 7 fixed to a shaft 8, supported or journaled in the upper end of said housing or casing, suitably driven, as will be later explained. Said shaft 6 has also secured to it a ratchet 9, and hung upon said shaft is a bellcrank 9 carrying a pawl or dog10,havinglat eral engagement with said ratchet and spring connection 6 with said ratchet, said pawl or dog also having a rearward extension or arm 10 for engagement with a tripping-plate 11 to disengage said pawl from said ratchet after said pawl has suitably actuated said ratchet to impart, as later made apparent, the requisite interval of movement to the grain-measuring cylinder. Said tripping-plate is suitably pivoted or hung upon a stud or projection on the housing or casing of the elevator 1 and is upheld by a deflected or offset stud 12 on the brace 3"". A pitman 13 has connection with the right-angled arm 10 of the bellcrank 9 by means of a loose crank-arm or link 13, pivoted to said arm and having like connection with said pitman,,said parts again being referred to later.

A cam-groove 14, in outline preferably an equilateral triangle, is produced in a casting 1 1, secured upon the upper edge of the radial partitions of the compartments of the measuring-cylinder 2 at the center or point of union between said partitions, said triangle or groove having at each angle or corner a socket or depression 1 1, extending a short distance below the bottom of said groove, the purpose of which will be apparent presently. The cam-groove casting-14S is held centrally in position and the cylinder 2 poised upon its bottom pivot or pin 3 by means of a second pivot 15, which may be a headed removable pin engaging a central socket or aperture 15 in said casting and passed through coincident apertures in a preferably stepped cross-bar or arm 15, projecting laterally from and integral with the scraper 5 and secured to the opposite arm or bar 3", said latter apertures being brought into such coincidence by reason of one being produced in an overhanging portion of the upper step of said arm or cross-bar. This, however, is a matter of detail and may not be strictly adhered to in providing for the reception of said upper pivot or pin 15, although being preferable for promoting stability for this purpose. Said equilateral triangular slot 14: receives a downward-extended projection or terminal 13 of the pitman 13,within which it has movement or plays, as presently seen.

An additional elevator or conveyer 16 is supported or pivoted, as at 16, at its lower end upon the deck or top of the threshingmachine and suitably braced in position as shown or otherwise, said elevator having the lower end. of its housing or casing upturned ing said grain as aforesaid.

and forming a chute, as at 16", with its receiving end opposed to the under side of the measuring-cylinder directly in alinement with the opening in the bottom plate 3, through which the grain from the compartments of said cylinder is discharged to receive such grain. Said elevator is belted, as at 7 similarly as the elevator 1, with the shaft 8 for its actuation and the elevation of its contents for delivery ultimately into a spout .or chute 18 for use in directing or delivering the grain into a wagon or otherwise disposing of the grain, as will be readily understood. Said chute or spout, preferably cylindric in cross-section, has pivoted to its upper end a horizontally-movable coupling or elbow-section 18, having depending from its under side a fixed pivot or pintle 18", entering or engaging a socket 18 in a bar or arm 18, projecting from and fixed to the housing or casing of the elevator 16, said elbow-section or coupling telescoping a nozzle or sleeve 18 also cylindric in cross-section and fixed to the upper or delivering end of said elevator to receive the grain therefrom and trans-- fer it, via said elbow-section, to said chute or spout for the purpose aforesaid. This arrangement permits the ready placing in posi- .removal, as well as the lateral movement of the latter for convenience in suitably shiftving the point of delivery of the grain therefrom.

It will be noted that the shaft 6 being continually in motion, being suitably driven from the threshing-machine, by the time the pawl or dog 10 has moved the ratchet 9 so as to elfect engagement between its extension 10 and the tripping device 11 the compartment of the measuring cylinder or receptacle receiving the grain via the spout or chute 1 from the elevator 1 will have been filled, and the pitman 13, previously so moved by the action of the same parts as to permit its terminal 13 to engage a socketor depression 14 of the groove 14, will move by such engagement said cylinder, so as to bring its thus filled compartment into coincidence with the opening in the bottom plate 3, and thus permit the discharge of its contents therethrough into the chute 16 of the elevator 16, deliver- Simultaneously with the movement thus given to said measuring-cylinder it will be also noted that the scraper 5 will remove or stroke the surplus or overflow grain from the compartment which has been filled off into the adjoining or succeeding compartment of said cylinder, also that the weight of the weighted lever 4P, having been overcome by the contents of the grain in the filled cylinder-compartment, said lever Will be elevated, and being suitably connected up with a. recorder (not shown) a tally will be kept of the measured grain. Also it will be seen that such elevation of said lever 1 is permitted by the tilting or pivotal action resulting from the mobile connection, as at 3,be tween the arms 3 and their support 3 After the dumping or discharging of the contents of said cylinder or measuring compartment the dog or pawl 10 will have been released from the trip 11 and again be sprung by its spring 6 into engagement with the ratchet 9, while simultaneously therewith the pitman 13 will be moving or backing through another arm of the triangular slot 14 and finally enter or drop into another socket 1e thereof, providing for a repetition of the aforesaid operation of parts and the measuring and discharging of the contents of a second cylinder-compartment, and so on, as long as the machine is actuated.

From the foregoing the salient features of my invention will be apparent, among which it is seen that the whole operation of filling the compartments of the measuring-cylinder,

the stroking or scraping off the overflow or surplus grain, and the passing of such overflow grain into a succeeding compartment, and the actuation of the parts, so as to provide for the recording of the measured grain, and the discharging of such grain, is all elfected automatically with facility continuously and effectively. Also it is observed that increased facilities are obtainable by my invention for the delivering of the measured grain and the loading of the same upon means of its transportation or otherwise disposing of such grain temporarily, as may be desired.

Latitude is allowed as to details herein, and they may be accordingly changed as circumstances suggest without departing from the spirit of my invention and said invention still remain protected.
